Diagnosis

Internal structure similar to that of Hymeniastrum euclidis; central region larger, with 5-10 concentric, latticed, discoidal shells; arms with 10-16 concentric rings. Arms much broader proximally than in the preceding species with a much shorter region of narrow breadth; terminations of arms spatulate or lanceolate, coming to a point distally in fully developed forms. Position of arms variable from nearly equally disposed to bilaterally disposed; generally a larger distinct odd arm present. A layered spongy patagium either partially developed, rudimentary, or absent; no specimens were observed with fully developed patagium, but in those with patagium partially developed it showed no increase in its thickness distally.
